“… 3 Other endovascular options for management of type Ia endoleaks, with still uncertain long-term durability include embolization using coils, glue ( n -butyl cyanoacrylate), or liquid embolic agents such as Onyx. 5 – 7 Further endovascular methods include chimney grafts and fenestrated or branched endografting (fEVAR/bEVAR). 8 , 9 Chimney grafts may lead to gutter-related endoleaks.…”

Purpose Open surgical repair of type Ia endoleak after endovascular aortic aneurysm repair/sealing (EVAR/EVAS) is associated with significant perioperative mortality and morbidity. Current endovascular redo techniques face limitations, especially when the infrarenal landing zone is inadequate and the previous endograft is rigid and features a short or no main body. We present a novel concept for the treatment of type Ia endoleak using a custom-made branched device. Technique The 5-branch-device (Cook Medical, Bloomington, IN, USA) consists of a nitinol skeleton with branches, covered with a low-profile polyester fabric loaded in an 18F sheath. The device features a minimum of 2 proximal sealing stents and includes branches for renovisceral vessels as well as an additional 8 mm branch for the contralateral iliac limb. Implantation and sealing in the renovisceral vessels is carried out in standard fashion, using transfemoral and transaxillary access. Distal sealing is achieved by tapering the branched component into the ipsilateral iliac limb and using a bridging balloon-expandable or self-expandable stent-graft through the additional branch to the preexisting contralateral iliac limb. Conclusion Treatment of type Ia endoleak with a new custom-made device enables sufficient proximal seal while minimizing suprarenal aortic coverage and facilitates adequate component overlap. The low profile branched design accommodates implantation through the preexisting endograft and catheterization of target vessels.

Embolization for Type Ia Endoleak after EVAR for Abdominal Aortic Aneurysms: A Systematic Review of the Literature

et al. 2022

(1) Successful endovascular repair for abdominal aortic aneurysms is based on the complete exclusion of the aneurysm sac from the systemic circulation. Type Ia endoleak (ELIA) is defined as the persistent perfusion of the aneurysm sac due to incomplete proximal sealing between aorta and endograft, with a consequent risk of rupture and death. Endoleak embolization has been sporadically reported as a viable treatment for ELIA. (2) A systematic literature search in PubMed of all publications in English about ELIA embolization was performed until February 2022. Research methods and reporting were performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Data regarding patient numbers, technical success (endoleak absence at control angiography), reinterventions, clinical and imaging follow-up, and outcomes were collected and examined by two independent authors. (3) Twenty-one papers (12 original articles, 9 case reports) reported on 126 patients (age range 58–96 years) undergoing ELIA embolization 0–139 months after the index procedure. Indication for embolization was most often founded on unfavorable anatomy and patient comorbidities. Embolic agents used include liquid embolic agents, coils, plugs and combinations thereof. Technical success in this highly selected cohort ranged from 67–100%; the postprocedural complication rate within 30 days was 0–24%. ELIA recurrence was reported as 0–42.8%, with a secondary ELIA-embolization-intervention success rate of 50–100%. At a follow-up at 0–68 months, freedom from sac enlargement amounted to 76–100%, freedom from ELIA to 66.7–100%. (4) Specific literature about ELIA embolization is scant. ELIA embolization is a valuable bailout strategy for no-option patients; the immediate technical success rate is high and midterm and long-term outcomes are acceptable.
